Key ECS metrics to monitor

Amazon Elastic Container Service (ECS) is an orchestration service for Docker containers running within the Amazon Web Services (AWS) cloud. It allows users to declare the components of a container-based infrastructure, and ECS will deploy, maintain, and remove those components automatically. The resulting ECS cluster lends itself to a microservice architecture where containers are scaled and scheduled based on need. ECS integrates with other AWS services, allowing for features such as routing container traffic through Elastic Load Balancing or attaching an Auto Scaling policy to your ECS deployment. It also works with Fargate, which lets users deploy their containers straight to the AWS cloud without needing to provision EC2 instances. Monitoring in layers is important when using ECS, and two groups of metrics provide comprehensive visibility across every layer of your ECS infrastructure: resource metrics and status metrics. These metrics help ensure the availability and performance of your ECS deployment.
